3 You can access the device via "My Computer" on your PC. If your phone does not mount automatically, touch the USB icon that appears in the menu bar at the top of the display, drag it down to expose the Android Notification Panel, then tap on "USB Connected" and select "Mount" (or "Disk Drive").

4 Navigate to your Android phone's root directory and transfer the ringtones to either of the following folders:
/media/ringtones
/media/notifications
/media/alarms
If these folders do not exist, you can use window explorer to create them yourself.

5 Disconnect your phone, and you are ready to use the new ringtones. If you don't see the ringtone you just added, just reboot the phone.
